Planck PR2 SZ Cluster MMF1 List: Galaxy Cluster Candidates

Planck Data Release 2 contains catalogs of galaxy cluster candidates detected via the Sunyaev-Zel'dovich effect. The data includes results from three independent detection pipelines, with the main catalog providing coordinates, signal-to-noise ratios, and external validation information. The National Aeronautics and Space Administration released this component of the Planck mission data.

Use Cases

• Validating galaxy cluster detection algorithms based on the distinct spectral signature of the SZ effect.
• Cross-matching candidate clusters with external optical or X-ray surveys based on provided coordinates and validation info.
• Assessing pipeline consistency by comparing results from the three independent detection methods (MMF1, MMF3, PwS).
• Studying the statistical properties of SZ-selected clusters based on signal-to-noise ratios.

Strengths

• Data originates from the Planck satellite mission, a major space observatory.
• Includes results from three independent detection pipelines (MMF1, MMF3, PwS) for expert assessment.
• Provides external validation information, including redshift where available.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
